Abstract: A decentralized investment fund operates according to consensus code on a shared ledger and raises capital by issuing ownership tokens on the shared ledger. The decentralized investment fund may hold digital assets in the consensus code and distribute profits to the token owners according to each owner's dividend preference. A token owner's dividend preference can include digital assets tracked by a different shared ledger, stabletoken digital assets pegged to the value of a digital asset, and cross-chain digital asset swaps. Token issuance may include a proof of accreditation requirement based on cryptographic proof on a shared ledger. The decentralized investment fund may distribute fund documents to the token holders by encrypting the document, first with a symmetric key common to all token holders, and second with an asymmetric key unique to each token holders and based on the token's holder's known public address on the shared ledger.

Abstract: A system for “tagging” funds identified on a blockchain and associating a weight value therewith. The tagging profile is developed into a propagation profile wherein weight values are inherited from the tagging profile s. Propagation profile funds may be diluted by combining with non-tagged funds, similar to how ink dilutes through water. A spending history of funds of interest is developed based on replaying the funds of interest against the global transaction history of the blockchain. It is determined whether the spending history intersects with the propagation profile, thus determining how closely the two sources of funds are economically to one another. Intersection triggers actions including alert notifications or transfer of funds on the blockchain.
